Welcome to Online TI-84 (onlineti84.com) — a free, browser-based TI-84 style graphing calculator made for students, teachers, and anyone who needs reliable math tools without buying an expensive device.
What We Offer
Onlineti84.com gives you a full TI-84 style calculator right in your browser. You can graph functions, solve equations, explore tables of values, and work with statistics — all without downloading anything, installing software, or creating an account. It works on phones, laptops, and Chromebooks, so your calculator is available wherever you study.
Our calculator includes graphing with up to six functions, window and zoom controls, trace, degree and radian modes, zero, minimum, maximum and intersect calculations, tables of values, one-variable and two-variable statistics, linear and quadratic regression, fractions, derivatives, integrals, and matrix tools. Step-by-step guides on this website explain how to use each feature, just like you would learn in class.
Why We Built This
The TI-84 Plus and TI-84 Plus CE are among the most popular calculators in schools and colleges, but not everyone has access to one at all times. They are expensive, and they are easy to forget at home or in a locker. We built onlineti84.com so that any student can open a browser and practise the same TI-84 steps they learn in class — for homework, revision, and exam preparation — completely free.
Who Is It For
Our calculator is made for high school and college students studying algebra, geometry, statistics, precalculus, and calculus, for teachers demonstrating concepts in class or online, and for professionals who need a quick, dependable graphing calculator on the go.
